Description

Technical Field

[0001] This invention relates to the field of air conditioner sheet production technology, specifically to a molding device for co-extrusion production of air conditioner sheets. Background Technology

[0002] Currently, extrusion production lines can be used to produce various plastic pipes, plastic sheets, and plastic plates, and have a wide range of applications. Air conditioner panels are also usually co-extruded panels. During production, the extruded panels are passed through corresponding extrusion rollers, and then the distance between the extrusion rollers is adjusted to extrude and shape the semi-finished flooring.

[0003] The invention disclosed in CN118181622A uses a drive assembly to drive the adjustment part and the heat conduction part to reciprocate, which can squeeze the same position of the floor multiple times. This allows the adjustment part to improve the yield rate of adjusting the size and thickness of the floor, and the heat conduction part to make the film and the floor adhere better.

[0004] As described in the invention above, multiple extrusion rollers are usually used for extrusion. However, after prolonged use, mechanical failures, raw material problems, and inadequate lubrication and maintenance may cause the extrusion rollers to fail to roll smoothly or rotate. In this case, the extrusion rollers will obstruct the movement of the sheet material and cause wear on the sheet material, reducing the quality of the sheet material. Furthermore, friction will generate heat, reducing the cooling efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a molding apparatus for co-extrusion production of air conditioning sheet materials.

[0006] This invention adopts the following technical solution: a molding device for co-extrusion production of air conditioning sheet metal, comprising a molding box, a connecting plate on one side of the molding box, the connecting plates being symmetrically arranged on both sides, an upper extrusion roller and a lower extrusion roller being arranged between the two opposing connecting plates, a vacuum pump being fixedly connected to the upper end of the connecting plate, and lifting grooves being provided on the upper and lower sides of the opposite sidewalls of the connecting plate, further comprising: An anti-friction mechanism is provided to move the upper extrusion roller away from the sheet metal when the rotation of the upper and lower extrusion rollers is obstructed. The anti-friction mechanism is located inside the connecting plate. It also includes an automatic pressure regulating mechanism that can automatically adjust the pressure, and the automatic pressure regulating mechanism is located inside the anti-friction mechanism.

[0007] As a further description of the above technical solution: the anti-friction mechanism includes a lifting block, which is slidably disposed on the opposite sidewalls of two connecting plates, and each connecting plate has two lifting blocks disposed on its sidewall. The lifting block is provided with fastening bolts. An air jet groove is formed on the sidewall of the lifting block near the upper extrusion roller. A lifting connecting rod is movably disposed on the sidewall of the lifting block. The upper and lower extrusion rollers are rotatably disposed at one end of the upper and lower lifting connecting rods. A sliding block is horizontally slidably disposed inside the lifting block, and the sliding block is slidably disposed vertically within the lifting connecting rod. A limiting rod is inserted into the sliding block, one end of which is fixed to the lifting block. A limiting plate is fixed to one side of the sliding block on the lifting block. A ventilation groove is horizontally opened inside the sliding block. A trapezoidal rod is inserted vertically inside the sliding block. One end of the lifting connecting rod is fixed to the trapezoidal rod. The upper end of the trapezoidal rod abuts against the limiting rod. The lower end of the trapezoidal rod extends into the ventilation groove. A fixing rod is horizontally inserted into the ventilation groove. The end of the fixing rod away from the limiting rod is fixed to the lifting block. A magnetic block one is inserted vertically inside the sliding block. A magnetic block two is fixed to the lower side of the sliding block inside the lifting block.

[0008] As a further description of the above technical solution: the automatic pressure regulating mechanism includes a jet port, and there are two jet ports. The two jet ports connect the sliding cavity where the sliding block is located to the outside of the lifting block. A connecting port is opened in the fixed insertion rod. An air outlet is connected to the connecting port. One end of the connecting port is connected to the air vent, and the other end of the connecting port is connected to a hose. The hose is connected to the air pump.

[0009] As a further description of the above technical solution: several upper and lower extrusion rollers are arranged at equal horizontal intervals, and the upper and lower lifting blocks are arranged symmetrically.

[0010] As a further description of the above technical solution: both the fixed insertion rod and the trapezoidal rod have inclined sliding surfaces at their opposite ends.

[0011] As a further description of the above technical solution: initially, the bottom end of the trapezoidal rod can block the ventilation groove.

[0012] As a further description of the above technical solution: the opposite ends of the second magnetic block and the first magnetic block can generate an attractive force.

[0013] As a further description of the above technical solution: the connecting port and one of the jet ports are located near the sliding block.

[0014] This invention provides an improved molding apparatus for co-extrusion production of air conditioning sheet metal, which has the following improvements and advantages compared with the prior art: Firstly, when the upper and lower extrusion rollers rotate normally, air is drawn out of the lifting block through the hose, connecting port, air outlet and jet nozzle to assist the upper and lower extrusion rollers in cooling the board and improve the cooling speed. When the upper or lower extrusion rollers become obstructed after long-term use, the air can push the trapezoidal rod to move. The air compression can make the upper and lower extrusion rollers move away from the board automatically when the friction force on the upper and lower extrusion rollers is too large. Secondly, it can prevent excessive squeezing pressure between the sliding block and the limiting plate when the upper and lower squeezing rollers are rolling normally, thus preventing squeezing damage. Furthermore, the squeezing of gas can replace elastic materials such as springs, preventing fatigue of elastic materials. In summary, when the upper and lower extrusion rollers rotate normally, air is drawn out of the lifting block through the hose, connecting port, air outlet, and jet nozzle to assist the upper and lower extrusion rollers in cooling the sheet material and improve the cooling speed. When the upper or lower extrusion rollers experience rolling obstruction after prolonged use, the air can push the trapezoidal rod to move. The air compression can automatically move the upper and lower extrusion rollers away from the sheet material when the friction force on them becomes too large, which can effectively prevent wear on the sheet material and improve the quality of the sheet material. It can also prevent excessive extrusion force between the sliding block and the limiting plate when the upper and lower extrusion rollers are rolling normally, preventing extrusion damage. Furthermore, the air compression can replace elastic materials such as springs, preventing fatigue of elastic materials. Attached Figure Description

[0017] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Please see Figure 1 - Figure 7 This invention provides a technical solution: a molding device for co-extrusion production of air conditioning sheet metal, comprising a molding box 1, a connecting plate 2 on one side of the molding box 1, the connecting plates 2 being symmetrically arranged on both sides, an upper extrusion roller 3 and a lower extrusion roller 5 being arranged between the two opposing connecting plates 2, a vacuum pump 4 being fixedly connected to the upper end of the connecting plate 2, and lifting grooves 6 being provided on the upper and lower sides of the opposite sidewalls of the connecting plate 2, and further comprising: The anti-friction mechanism 7 can move the upper extrusion roller 3 away from the plate when the rotation of the upper extrusion roller 3 and the lower extrusion roller 5 is obstructed. The anti-friction mechanism 7 is set inside the connecting plate 2. And an automatic pressure regulating mechanism 8, which can automatically adjust the pressure, is located inside the anti-friction mechanism 7.

[0019] Specifically, when the upper extrusion roller 3 and the lower extrusion roller 5 rotate normally, air is drawn out of the lifting block 71 through the hose 75, the connecting port 82, the air outlet 83, and the air jet port 81 to assist the upper extrusion roller 3 and the lower extrusion roller 5 in cooling the sheet material and improving the cooling speed. When the upper extrusion roller 3 or the lower extrusion roller 5 becomes obstructed after long-term use, the air can push the trapezoidal rod 711 to move. The air compression can cause the upper extrusion roller 3 and the lower extrusion roller 5 to move away from the sheet material when the friction force is too large. This can effectively prevent wear on the sheet material and improve the quality of the sheet material. It can also prevent the excessive extrusion force between the sliding block 77 and the limiting plate 78 when the upper extrusion roller 3 and the lower extrusion roller 5 are rolling normally, preventing extrusion damage. In addition, the gas compression can replace elastic materials such as springs to prevent fatigue of elastic materials.

[0020] In another embodiment of the present invention, the anti-friction mechanism 7 includes a lifting block 71, which is slidably disposed on the opposite sidewalls of two connecting plates 2. Each connecting plate 2 has two lifting blocks 71 disposed on its sidewall. The lifting block 71 is provided with a fastening bolt 72. An air jet groove 73 is provided on the sidewall of the lifting block 71 near the upper extrusion roller 3. A lifting connecting rod 74 is movably disposed on the sidewall of the lifting block 71. The upper extrusion roller 3 and the lower extrusion roller 5 are rotatably disposed at one end of the upper and lower lifting connecting rods 74. A sliding block 77 is horizontally slidably disposed inside the lifting block 71. The sliding block 77 is slidably disposed inside the lifting connecting rod 74. A limiting rod 76 is movably inserted into the sliding block 77. One end of the limiting rod 76 is fixed to the lifting block 71. One side of the sliding block 77 is fixed to the lifting block 71 with a limiting plate 78. A ventilation groove 712 is horizontally opened in the sliding block 77. A trapezoidal rod 711 is inserted vertically in the sliding block 77. One end of the lifting connecting rod 74 is fixed to the trapezoidal rod 711. The upper end of the trapezoidal rod 711 abuts against the limiting rod 76. The bottom end of the trapezoidal rod 711 extends into the ventilation groove 712. A fixed insert rod 713 is horizontally inserted in the ventilation groove 712. The end of the fixed insert rod 713 away from the limiting rod 76 is fixed to the lifting block 71. A magnetic block 79 is inserted vertically in the sliding block 77. A magnetic block 710 is fixed to the lower side of the sliding block 77 in the lifting block 71.

[0021] Several upper extrusion rollers 3 and lower extrusion rollers 5 are arranged horizontally at equal intervals, and upper and lower lifting blocks 71 are arranged symmetrically.

[0022] Both the fixed insertion rod 713 and the trapezoidal rod 711 have inclined sliding surfaces at their opposite ends.

[0023] Initially, the bottom of the trapezoidal rod 711 can block the vent 712.

[0024] The opposing ends of magnetic block 710 and magnetic block 79 can generate an attractive force.

[0025] Specifically, when the upper extrusion roller 3 and the lower extrusion roller 5 rotate normally, air is drawn out of the lifting block 71 through the hose 75, the connecting port 82, the air outlet 83 and the air jet port 81 to assist the upper extrusion roller 3 and the lower extrusion roller 5 in cooling the board and improving the cooling speed. When the upper extrusion roller 3 or the lower extrusion roller 5 becomes obstructed after long-term use, the air can push the trapezoidal rod 711 to move. The air compression can make the upper extrusion roller 3 and the lower extrusion roller 5 automatically move away from the board when the friction force on them is too large, which can prevent wear on the board in a timely and effective manner and improve the quality of the board.

[0026] In another embodiment of the present invention, the automatic pressure regulating mechanism 8 includes two jet ports 81. The two jet ports 81 connect the sliding cavity where the sliding block 77 is located to the outside of the lifting block 71. A connecting port 82 is opened in the fixed insertion rod 713. An air outlet 83 is connected to the connecting port 82. One end of the connecting port 82 is connected to the air vent 712, and the other end of the connecting port 82 is connected to a hose 75. The hose 75 is connected to the air pump 4.

[0027] The connecting port 82 is positioned near one of the jet ports 81, close to the sliding block 77.

[0028] Specifically, it can prevent excessive squeezing pressure between the sliding block 77 and the limiting plate 78 when the upper squeezing roller 3 and the lower squeezing roller 5 are rolling normally, thus preventing squeezing damage. Furthermore, the gas squeezing can replace elastic materials such as springs, preventing fatigue of elastic materials.

[0029] Working principle: When using this device, the sheet material formed in the forming box 1 passes between the upper extrusion rollers 3 and the lower extrusion rollers 5. The upper and lower positions of the lifting block 71 are then adjusted by the fastening bolts 72. After adjustment, the fastening bolts 72 are fixed, and the upper extrusion rollers 3 and the lower extrusion rollers 5 press the sheet material together. When the sheet material continues to be transported, the upper extrusion rollers 3 and the lower extrusion rollers 5 continue to rotate. At this time, the air pump 4 can draw air out of the lifting block 71 through the hose 75, the connecting port 82, the air outlet 83 and the air jet port 81 to assist the upper extrusion rollers 3 and the lower extrusion rollers 5 in cooling the sheet material. When the upper extrusion roller 3 or lower extrusion roller 5 has been used for a long time, during the production process, it may experience rolling obstruction or failure to roll. This is difficult to detect during production and is not easy to replace. When the upper extrusion roller 3 or lower extrusion roller 5 rotates too slowly, the rolling friction between the sheet material and the upper extrusion roller 3 or lower extrusion roller 5 will become sliding friction. At this time, the upper extrusion roller 3 or lower extrusion roller 5 with the problem will cause the sliding block 77 to move towards the fixed insertion rod 713 due to the increased friction. Then, the air outlet 83 enters the ventilation groove 712 and is blocked. Then, the limit rod 76 disengages from the upper side of the trapezoidal rod 711. At this time, the magnetic block 79 moves to On the upper side of magnetic block 710, magnetic block 79 is attracted to the lower slot by magnetic block 710 to prevent the sliding block 77 from moving during subsequent air blowing. Then, the gas drawn in by the air pump 4 will be blown into the ventilation slot 712 through the connecting port 82. The gas will blow the trapezoidal rod 711 upward. After the trapezoidal rod 711 moves upward, the gas will be ejected from the lifting block 71 through the ventilation slot 712 and the air jet slot 73. The ejected gas can replace the roller that is far away from the plate to continue cooling the plate. At the same time, the upper extrusion roller 3 or lower extrusion roller 5 that is obstructed from rotating will automatically move away from the plate, which can effectively prevent wear on the plate and improve the quality of the plate. Furthermore, when the sliding block 77 does not cover the air jet 81, the air ejected from the air outlet 83 exerts a relatively small squeezing force on the sliding block 77 toward the limiting plate 78. As the sliding block 77 gradually covers the air jet 81, the air jet channel becomes smaller, and the rated power of the air pump 4 is constant. At this time, the squeezing force of the gas on the sliding block 77 toward the limiting plate 78 increases. This prevents excessive squeezing force between the sliding block 77 and the limiting plate 78 when the upper squeezing roller 3 and the lower squeezing roller 5 are rolling normally, thus preventing squeezing damage. Moreover, the squeezing of the gas can replace elastic materials such as springs, preventing fatigue of elastic materials. The squeezing of the air can cause the upper squeezing roller 3 and the lower squeezing roller 5 to move away from the plate only when the frictional force on them becomes too large.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
